OLFA 28mm Rotary Replacement Blades – Tungsten Steel, 2-Pack for Precision Cutting

OLFA RB28-2 are precision 28mm rotary replacement blades made from tungsten tool steel, sold as a two-blade refill pack for fine, long-lasting cutting.

These replacement blades are engineered for hobbyists, sewists, quilters, and craft professionals who need a smaller rotary blade for detailed work. Crafted from durable tungsten tool steel, each 28mm disc keeps an accurate edge for extended use and snaps into most 28mm rotary cutters—delivering neat, controlled cuts through fabric, paper, leather, and layered materials.

How sharp and durable are these 28mm blades?

OLFA's tungsten tool steel construction provides a sharp, wear-resistant edge that stays effective longer than basic carbon or stainless options. You’ll notice smoother cuts and fewer nicks near corners and intricate shapes.

• Made from tungsten tool steel for superior edge retention
• Precision-ground edge for clean slicing of thin and layered materials
• Reduced need for frequent blade swaps in typical crafting sessions

Will these fit my rotary cutter?

RB28-2 blades are designed for standard 28mm rotary cutters and perform best when paired with an OLFA 28mm rotary cutter. They also install easily into many other brands that accept 28mm circular blades.

• Compatible with most 28mm rotary cutters
• Optimised performance when used with OLFA 28mm cutters
• Simple replacement procedure—remove the old blade, position new disc, and secure

What kinds of projects are these small blades best for?

The 28mm size is ideal for detailed and confined cutting tasks where a larger wheel would be unwieldy. Use them for tight curves, small pattern pieces, appliqué, and other jobs that demand close control.

• Precise trimming for quilting blocks and fabric appliqués
• Clean cuts on paper, felt, leather swatches, and craft foam
• Perfect for miniature sewing projects, tight corners, and pattern work

How should I care for and change these replacement blades?

Handle with caution and follow safe blade-changing steps. Keep blades dry and stored in their original container to protect the edge, and replace when cutting becomes uneven or requires more pressure.

• Always remove the cutter’s guard and secure the wheel before swapping blades
• Store unused blades in their pack to avoid dulling and accidental cuts
• Inspect for chips or nicks and replace if you see irregular cuts

Who is this for? Makers who value accuracy and control will appreciate the OLFA RB28-2 two-blade pack: quilters trimming small pieces, crafters working miniatures, leatherworkers making small cuts, and hobbyists who need a compact rotary blade for detailed projects. If your work regularly requires tight curves, fine trimming, or layered material slicing, these tungsten-steel 28mm blades deliver consistent, clean performance.
